Description

Technical Field

[0001] This utility model belongs to the technical field of mining vehicles, specifically relating to a fixing device for boiler heaters in non-road wide-body mining vehicles. Background Technology

[0002] When off-road wide-body mining trucks are used in extremely cold regions, the engine cold start requires the use of a boiler heater for auxiliary heating.

[0003] The existing boiler heater fixing devices are not only cumbersome to install, but also easily affect the pipeline layout of the boiler heater, resulting in complex pipeline layout, difficulty in maintenance and replacement, and long preheating time. In addition, the existing boiler heater fixing devices are only used for installation and fixation, and have no protective function for the boiler heater. As a result, the boiler heater is easily damaged in the harsh operating environment of off-road wide-body mining vehicles, increasing the operating cost of the vehicle. Utility Model Content

[0004] This utility model provides a fixing device for boiler heaters in non-road wide-body mining vehicles, which solves the technical problems of existing boiler heater fixing devices being cumbersome to install, affecting pipeline layout, and lacking protective function.

[0005] This utility model includes: at least two boiler heater bracket welding assemblies, each boiler heater bracket welding assembly including a vertical section and a horizontal section located below the vertical section, and at least two boiler heater bracket welding assemblies are respectively mounted side by side on the vehicle frame through their respective vertical sections;

[0006] The horizontal section points to the inside of the frame and is used to house the boiler heater assembly;

[0007] The boiler heater baffle welding assembly is located on the outer side of the vertical section.

[0008] This utility model fixes the boiler heater assembly on one side by welding the boiler heater bracket assembly at the bottom of the frame. It is fixed on the outside of the boiler heater assembly, which will not interfere with the piping of the boiler heater assembly. In addition, it is combined with the boiler heater baffle welding assembly to protect the outside of the boiler heater assembly and prevent the outside of the boiler heater assembly from being hit.

[0009] Furthermore: the boiler heater bracket welding assembly includes:

[0010] Upper bending plate;

[0011] The lower bending plate is located on the rear side of the upper bending plate;

[0012] Two side plates are respectively provided on both sides of the upper bending plate and the lower bending plate;

[0013] The vertical section and the horizontal section of the upper bending plate are each provided with a number of mounting holes;

[0014] The top edge of the lower bending plate is provided with a clearance groove. The beneficial effects of this step are: the square cross-section boiler heater bracket welded assembly composed of the upper bending plate, lower bending plate and side plate has high structural strength and good stability. Moreover, since the upper bending plate, lower bending plate and side plate are all sheet metal structures, they are easier to produce and have lower production costs.

[0015] Furthermore, the two side plates are respectively recessed into the gap between the upper and lower bending plates. The beneficial effect of this step is that the recessed side plates can further improve the structural strength of the boiler heater support welded assembly.

[0016] Furthermore: the vertical section includes a first vertical section and a second vertical section, the second vertical section is outside the first vertical section, and the first vertical section and the second vertical section are connected by a transition horizontal section. The beneficial effect of this step is that the vertical section and the horizontal section form a C-shaped structure, which allows the boiler heater assembly to be more biased towards the outside of the frame, making it easier to install and maintain.

[0017] Furthermore, at least one first reinforcing rib is provided between the transition horizontal section and the second vertical section. The beneficial effect of this step is that the structural strength of the vertical section is increased by the first reinforcing rib.

[0018] Furthermore: the boiler heater baffle welding assembly includes a side baffle and a top baffle, and a second reinforcing rib is provided between the side baffle and the top baffle;

[0019] The side baffle also has several connection holes corresponding to the mounting holes. The beneficial effects of this step are: the side baffle can protect the side of the boiler heater assembly, the top baffle can protect the top surface of the boiler heater assembly, and the second reinforcing rib can support the top baffle and prevent the top baffle from collapsing.

[0020] Furthermore, the angle between the side baffle and the top baffle is greater than 90° and less than 160°. The beneficial effect of this step is that the top baffle is at an outward tilting angle. When an object falls on the top baffle from above, the tilted top baffle can dissipate part of the weight through its own structure, reducing the damage to the top baffle. It can also guide the object to the outside of the frame rather than the inside, preventing the object from flying into the inside of the frame and causing secondary damage to the pipelines and other parts inside the frame.

[0021] The beneficial effects of this utility model are:

[0022] 1. The boiler heater bracket welding assembly has a simple structure, is easy to assemble, and can be widely deployed in the vehicle. It will not affect the piping layout of the boiler heater assembly, so the total length of the relevant connecting pipes can be shortened, improving the preheating effect of engine cold start and saving preheating time.

[0023] 2. The boiler heater baffle welding assembly, combined with the boiler heater bracket welding assembly, can also provide good protection for the boiler heater assembly. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] Implementation of this application, for example Figures 1-5 As shown, this application provides a mounting device for a boiler heater on a non-road wide-body mining vehicle.

[0041] This utility model includes: at least two boiler heater bracket welding assemblies 4, each boiler heater bracket welding assembly 4 including a vertical section 45 and a horizontal section 46 located below the vertical section 45. At least two boiler heater bracket welding assemblies 4 are respectively mounted side by side on the frame 1 through their respective vertical sections 45. The side of the frame 1 has several through holes. The installation position of the boiler heater bracket welding assembly 4 on the frame 1 can be selected according to the actual installation situation of the vehicle. The number and spacing of the boiler heater bracket welding assemblies 4 can be selected according to the length of different models of boiler heater assemblies 2. For example, a shorter boiler heater assembly 2 can use two boiler heater bracket welding assemblies 4, and a longer boiler heater assembly 2 can use more than two boiler heater bracket welding assemblies 4.

[0042] The horizontal section 46 points to the inside of the frame 1, and the horizontal section 46 is used to house the boiler heater assembly 2;

[0043] The boiler heater baffle welding assembly 3 is located on the outer side of the vertical section 45.

[0044] This utility model fixes the boiler heater assembly 2 on one side by welding the boiler heater bracket assembly 4 at the bottom of the frame 1. It is fixed on the outside of the boiler heater assembly 2, which will not interfere with the pipe laying of the boiler heater assembly 2. In addition, it is combined with the boiler heater baffle welding assembly 3 to protect the outside of the boiler heater assembly 2 and prevent the outside of the boiler heater assembly 2 from being hit.

[0045] Based on the above technical solution, the boiler heater support welding assembly 4 includes:

[0046] Upper bending plate 41;

[0047] The lower bending plate 42 is located on the rear side of the upper bending plate 41;

[0048] Two side plates 43 are respectively provided on both sides of the upper bending plate 41 and the lower bending plate 42;

[0049] The vertical section 45 and the horizontal section 46 of the upper bending plate 41 are provided with a number of mounting holes. The mounting holes are used to place bolts and nuts to connect with the frame 1, the boiler heater assembly 2 and the boiler heater baffle welding assembly 3.

[0050] The top edge of the lower bending plate 42 is provided with a clearance groove;

[0051] The square-section welded assembly 4 of the boiler heater bracket, composed of the upper bent plate 41, lower bent plate 42, and side plate 43, has high structural strength and good stability. Furthermore, since the upper bent plate 41, lower bent plate 42, and side plate 43 are all sheet metal structures, they are easier to manufacture and have lower production costs. In addition, the connection point between the boiler heater bracket welded assembly 4 and the vehicle frame 1 bears the greatest load and needs to withstand vibrations generated during vehicle operation. Therefore, the lower bent plate 42 has a clearance groove to allow the bolts and nuts used to lock the vehicle frame 1 and the boiler heater bracket welded assembly 4 to tighten more securely.

[0052] Based on the above technical solution, the two side plates 43 are respectively recessed into the gap between the upper bending plate 41 and the lower bending plate 42. The recessed side plates 43 can make the frame structure in the cross section more compact and further improve the structural strength of the boiler heater bracket welding assembly 4.

[0053] Based on the above technical solution, the vertical section 45 includes a first vertical section 451 and a second vertical section 452. The second vertical section 452 is outside the first vertical section 451, and the first vertical section 451 and the second vertical section 452 are connected by a transition horizontal section 453. The vertical section 45 and the horizontal section 46 form a C-shaped structure, which allows the boiler heater assembly 2 to be more biased towards the outside of the frame, making it easier to install and maintain.

[0054] Based on the above technical solution, at least one first reinforcing rib 44 is provided between the transition horizontal section 453 and the second vertical section 452 to increase the structural strength of the vertical section 45.

[0055] Based on the above technical solution, the boiler heater baffle welding assembly 3 includes a side baffle 31 and a top baffle 32, and a second reinforcing rib 33 is provided between the side baffle 31 and the top baffle 32;

[0056] The side baffle 31 also has several connection holes 34 corresponding to the mounting holes. The side baffle 31 can protect the side of the boiler heater assembly 2, and the top baffle 32 can protect the top surface of the boiler heater assembly 2. The second reinforcing rib 33 plays the role of supporting the top baffle 32 and preventing the top baffle 32 from collapsing.

[0057] Based on the above technical solution, the angle between the side baffle 31 and the top baffle 32 is greater than 90° and less than 160°. The top baffle 32 is at an outward tilting angle. When an object falls from above onto the top baffle 32, the tilted top baffle 32 can dissipate part of the weight through its own structure, reducing the damage to the top baffle 32. It can also guide the object to the outside of the frame 1 rather than the inside, preventing the object from flying into the inside of the frame 1 and causing secondary damage to the pipelines and other parts inside the frame 1.

[0058] In the above embodiments, this application can fix the boiler heater assembly 2 without affecting the layout of its connecting pipes, without unnecessarily lengthening the pipe layout, thereby improving the preheating effect of the boiler heater assembly 2 on the engine and shortening the preheating time. Furthermore, the combination of the boiler heater bracket welding assembly 4 and the boiler heater baffle welding assembly 3 provides protection for the boiler heater assembly 2, preventing it from being damaged by flying ore or other objects.
